which the crosshead is vertically movable and is connected to a crank sha some distance below the lower end of said guide while the oil pump for the hoisting eng' is supported at or near the upper end of the engine cylinder and is operated by a continuous and somewhat slender pitman rod through the medium of an additional crank shaft which is located in approximately the horizontal plane of the crank shaft of the engine so that the connect rod between l we second-named cram and pump lever extends vertically p ly the entire distance from the oral of the engine to and above the top of ti cylinder.

In the practical operation of hoisting engines or cranes of this character it is found that after a relatively short period of use the vibration of the connecting rod between the pump lever and its crank shaft causes undue crystallization and resultant breakage of the rod near its connection with the crank shaft or near its connection with the pump lever due primarily to the excessive length of the rod.

The main object of the present invention is to reduce to a minimum this liability of breakage of any part or parts of the connection between the pump lever and its crank shaft by interposing in the connection alever of the first kind and connecting opposite ends of the lever to the crank shaft and to the pump lever respectively by short rods.

Another object is to support the pivot for the lever upon one of the studs with which the frame of the engine is provided.

Other objects and uses relating to specific parts of the device will be brought out in the following description.

In the drawings Figure 1 is a side elevation of a portion of an upright hoisting engine showing the oil pump and crank shaft and my improved connections between the crank shaft and pump lever.

Figure 2 is a transverse sectional view of a part ofthe same device taken on line 2-2. h

ed, this device comprises a t he li st kind journaled mid- )on a suitable bear- .rn supported upon a screw ended end of this screr' aded aperti i in it this 0 t D 611 i l irea ilci. end of a screw ich the aine as; A of the engine is a idy provided, the coupling iw rtly screwed upon the threaded end. or the stud --6-- and provided with a set screw T for tightening the coupling upon the inner end of the screw to hold the latter against turning.

in oil pnnip P irdicated more or less diagrammatically in gure 1 is mounted upon the engine frame near the upper end of the cylinder not sh wn, anc is provided with an operating lever 8 having a threaded outer end upon which mounted a collar capable of being adjusted to vary the throw of the pump part operated thereby.

The collar -9- is provided with trunnions upon which is journaled a forked yoke 1l, the latter being connected by a rod 12 to the underlying end of the lever 1- through the medium of a pivotal pin l3.

The other end of the lever 1 is connected by a rod -ll to a coupling member 15 which is pivoted at l6 to an engine-driven revolving member l8 the pivot 1G being located some distance to one side of the axis of the member -l8 and together with said member constituting a crank for reciprocating the rod l4t vertically.

This reciprocation of the rod l l imparts rocking movement to the lever -l, said rocking movement being transmitted to the pump operating lever 8-- through the medium of the rod 12 and yoke 11 which forms a part of the rod 12.

The oil pump my be of any wellknown oscillating type capable of feeding a lubricant to the cylinder and other parts of the engine if desired.

The object in employing the coupling member -i is to permit the lever 1- to be mounted upon the stud as 6- with which the engine is already equipped and atthe same time to support the lever in ap'-- proximately the vertical plane of the pump lever +8 and crank disk -l8- so that the entire driving connection between the crank shaft or disk 18 and pump will lie in substantially the same vertical plane.

Under this construction it is evident that the connecting rods -12 and 14 will be relatively short as compared with the distance between the crank shaft or operating member 18 and pump lever 8 which greatly reduces the vibration of those rods and incidentally prolongs the" life thereof. 7 V p 7 What I claim 1s: 1

1. In a journal mounting for a lever of the first kind, a sleeve internallv threaded in both ends, one end of said sleeve being ada ted to en ag'e an engine stud a screw the firstflrind, a sleeve internally threaded in'both ends, one end of said sleeve being adapted to engage an engine stud, a screw adapted to be threaded into the opposite end of said sleeve, the shank of said screw being provided with a bearing member of less diameter than the head of the screw, a lever journaled on such bearing, means for lockand means for ing said screw in said sleeve, and means for oiling said bearing.

In witness whereof I have hereunto set my hand this 23d day of January, 1926.
